Chapter 10.2, Problem 13E
Annual Cost of College. The increasing annual cost (including tuition, room, board, books, and fees) to attend college has been widely discussed (http://time.com/money/4543839/college-costs-record-2016/). The following random samples show the annual cost of attending private and public colleges. Data are in thousands of dollars.
- a. Compute the sample
mean and sample standard deviation for private and public colleges. - b. What is the point estimate of the difference between the two population means? Interpret this value in terms of the annual cost of attending private and public colleges.
- c. Develop a 95% confidence interval of the difference between the mean annual cost of attending private and public colleges.
